5 of us stayed at Sara's place and were very content throughout our stay. It was easy to find and the place looked exactly like the photos. There is a lift for your luggage but you have to walk up the stairs so I suggest requesting a room at lower floor if you are travelling with an elderly person.
Pradiphat has a number of money exchange stores and eateries (restaurants, cafes, convenience stores and many street food stalls). Sara's place is located in an alley that was private enough so you won't hear noise from the street and close enough to street so you can walk everywhere.
We took Grab cars to most places. Closest touristy place to this airbnb was Chatuchak market. Other times, we walked to the Saphwan Khai BTS and took the train (10 min walk from Sara's place). There is a Big C supermarket about 10 mins walk away.
I was very happy to experience a very smooth stay at Sara's place and recommend it for a small group of people!
